That isn’t the correct useage of terms there.
The gps signal is in fact satilite GPS… good maps and on the pre “sprint navigation” the route as well as the map are fed over the data…
In other words, your phone will know your “location” without data signal, but it won’t be able to show you it on a map that you can understand.
it shouldn’t take long before these phone can hold enough info to actually store all the info that tom tom or garmin units hold allowing them to be stand-alone without a data signal.
